CSRC
SREN/CREN overrides TXEN in Sync mode.
CSRC: Clock Source Select bit
Asynchronous mode:
Don’t care.
Synchronous mode:
1 = Master mode (clock generated internally from BRG)
0 = Slave mode (clock from external source)
TX9: 9-Bit Transmit Enable bit
1 = Selects 9-bit transmission
0 = Selects 8-bit transmission
TXEN: Transmit Enable bit
1 = Transmit enabled
0 = Transmit disabled
SYNC: EUSART Mode Select bit
1 = Synchronous mode
0 = Asynchronous mode
SENDB: Send Break Character bit
Asynchronous mode:
1 = Send Sync Break on next transmission (cleared by hardware upon completion)
0 = Sync Break transmission completed
Synchronous mode:
Don’t care.
BRGH: High Baud Rate Select bit
Asynchronous mode:
1 = High speed
0 = Low speed
Synchronous mode:
Unused in this mode.
TRMT: Transmit Shift Register Status bit
1 = TSR is empty
0 = TSR is full
TX9D: 9th Bit of Transmit Data
Can be address/data bit or a parity bit.
